DETACHA'.BLE DRAFT-TONGUE' FOR QUARRY-TRUCKS.

Specification of Letters Patent. Patented Dec. 28, 1909. Applicationfiled April 23, 1909; Serial No. 491,708. 4

To all whom it may concern:

Be it known that I, LOWRY W. STATLER, citizen of the United States,residing at Piqua, in the county of Miami and State of Ohio, haveinvented certain new and useful Improvements in Detachable Draft-Tonguesfor Quarry-Trucks, of which the following is a specification.

This invention relates to trucks and more particularly to a truckespecially designed for use in stone quarries for conveying blasted rockfrom the stone ledges to the crushing plant.

The object of the invention is to provide a quarry truck having a novelform of draft tongue capable of being readily attached to either end ofthe truck so that the latter may be caused to travel in either directionwith equal facility.

A further object is to provide a truck in which the tongue attachingmembers are extended longitudinally beyond the periphery of the adjacenttraction wheels thereby to permit the tongue or pole to be readilyattached to or detached from the vehicle without the necessity ofunhitching the team.

A further object is to provide the draft tongue or pole with dependingshoes having curved terminals constituting runners, which latter serveto prevent the double and swingletrees from coming in contact with theground when transporting the draft tongue from one truck to another.

- A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability, andefficiency.

Further objects and advantages pear in the following description, itbeing understood that various changes in form, proportions, and minordetails of construction may be resorted to within the scope of theappended claims.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a top plan view of a quarry truck constructed in accordancewith my invention, the detachable tongue being shown in full lines onone end of the truck and in dotted on the other; Fig. 2 is a perspectiveview of the rear portion of the tongue will apor draft device detached;Fig. 3 is a side elevation of the forward portion of the truck; Fig. 4is a top plan view of the truck with the detachable tongue removed; Fig.5 is a longitudinal sectional view of Fig. 4.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawings by the samereference characters.

The improved truck forming the subject matter of the present inventionincludes front and rear axles 5 and 6 on which are mounted tractionwheels 7 said axles being pivotally connected by diagonally disposedbraces 8 constituting a short turning gear. Extending laterally from theaxles 5 and 6 of the truck, are spaced supporting members or arms 9having their outer or free ends extended longitudinally beyond theperiphery of the adjacent traction wheels for attachment to the drafttongue or pole 10.

Interposed between the front and rear axles of the truck and preferablydisposed beneath the diagonal braces 8, are arcuate members 11 havingtheir opposite ends extended beneath the lower faces of the members 9and to which they are rigidly secured by bolts or similar fasteningdevices 12. The segmental bars 11 not only assist in supporting theattaching arms 9, but also form the hounds of the truck. The arms 9 arereinforced and strengthened by the provision of metallic plates 13, thefree ends of which are bent inwardly and upwardly in spaced relation tothe adjacent ends of the arms to form vertically disposed lugs 14, whichin conjunction with similar lugs 15 formed on the free ends of attachingplates 16 fastened on the tops of the arms, define sockets 17 for thereception of the cross arm or bar 18 of the draft tongue. The arms 9 arefurther reinforced and strengthened by inclined braces 19 the ends ofwhich are attached to the inner faces of the adjacent arms, while themiddle portion thereof is fastened in any suitable manner to the axle.

Attention is here called to the fact that the inclined braces 19 notonly serve to strengthen the arms 9, but also assist in maintaining thelatter in parallel relation to each other.

The draft tongue 10 is provided with the usual doubletree 20 andswingletrees 21 for attachment to the draft animals, whereby the truckmay be transported from the quarry to the crushing plant.

The cross bar or arm 18 of tllfi dlj itfll tongue is preferably formedofa flat strip of metal, the opposite ends of which are given ahalf turnto produceverticallydisposed p01 7 tions 22 adapted to enter the sockets17 at the peripheries or fellies of the adjacent traction wheels, thetongue may be readily attached to ordetached from the truck without thenecessity of first unhitching the draft animal or animals. n

The opposite ends of the cross bar or arm l 18 a'tthe twisted portions22 thereof, are extended laterally to produce oppositely disposed loopsor finger pieces 23 by means of which. said bar may be readilypositioned in I or removed. from the adjacent sockets .17.

Depending from the rear end of the draft tongue 10, preferably beneaththe bar 18, are shoes 24, the free ends of which are curved to formrunners 25 adapted to travel over the surface of the ground and thusspace the tongue from the ground and prevent the double and swingletrees fromcoming in contact therewith when transferring thetongue fromone truck to another. 7

Suitable inclined braces 26 are preferably extended from the inner orrear end of the 'track or incline leading tongue to the outer portionsof the bar 18, there belng similar inclined braces 27 form- 111gaconnection between the bar 18 and the 'side walls of the tongue 10 inadvance of the double-tree 20, as shown.

It is preferred to make the rims of the traction wheels half round incross section so that said wheels may travel on a concave from thequarry to the plant, the tread surface of the tires being such that thewheels may travel on the bed of the quarry in the usual manner withoutunnecessary jar or jolting to the contentsof the truck. Thus it will beseen that by graspingthe finger-pieces 23 and exerting a slight upwardpull 011 the bar 18, the vertical portions 22 of said bar may be readilydisengaged from the sockets 17 so as to permit thetongue to be movedfrom one end of the truck and placed in position on the other end of thetruck or on another truck when necessary. It will also be noted thatwhenthe tongue is detached from the truck, the curved faces or runners25 will bear against the ground and support the rear end of the tongueinelevated positionwhile the draft animals are moving the tongue fromone truck to another.

Having thus described the inventiomwhat is claimed as new is:

ll lhe combination with a wheeled truck,

attaching arms secured to the axle of the truck and 'having'their freeends projected longitudinally beyond ,the ,peripheral edges iter thesockets fordetachably securing the draft tongue imposition on {thetruck.

2. The combination \witha wheeled truck,

spaced arms secured to :the axle ofithe truck and having their free endsprojected longitudinally beyond the adjacent traction wheels, a platesecured to one side of each arm and having its free end bent upwardly:to :form a vertically disposed lu'g, a ,plate 7 secured to the top :ofeach ;arm yandprovided with a similar lug forming in conjunction withthe matingluga-socket, a draft tongue detachably secured to the truckand atrans. verse bar carried by the draft tongue and provided withterminal finger-pieces,-the intermediate portions :of :the transversebar being twisted to produce vertical portions arranged to enter the adjacentjsockets.

3. The combination with a wheeled truck having bounds, the ends ,ofavhich are extended beneath and beyond the adjacent aXles, -arms secured,to the, extended portions of :the adjacent hounds, co-acting platessecured :to each arm and having .their free ends extended longitudinallybeyond the; ad-

jacent-traction .wheels and bent upwardly to produce vertically disposedlugs, bracesextending between the @inner :faces of the arms and theadjacent ;aXle, ;a draft tongue transverse =bar secured to .thepinnerend of the tongue, and having its opposite ends twisted to form verticalportionsnrranged.

to gfit between the lugs of the-adjacent arms, said cross barterminating in ;finger-,pieces, and shoes depending having their .lowerportions curved laterally to produce bearing surfaces.

4. A draft device for vehicles, comprising a :tongue, a transverselydisposed bar secured to one end of the tongue and having itsv oppositeends provided withfinger-pieces, braces extending between the transversebar and vthe adjacent longitudinal edges of the tongue, and shoesdepending from the tongue in advance of the bar and provided with curvedcontact faces, that portion of the transverse bar near the fingerspiecesbeing twisted to produce vertically idisposed portions forengagementwith avehicle.

In testimony whereof I affix my signature in presence of two witnesses.
